将宽字符串wcstr转换为ANSI字符串mbstr size_t wcstombs( char *mbstr, const wchar_t *wcstr, size_t count ); mbstr 多字节字符的地址 wcstr 宽字符的地址 count 可以存储在多字节字符的最大字节数 将ANSI字符串mbstr转化为宽字符串wcstr size_t mbstowcs( wchar_t *wcstr, const char *mbstr, size_t count ); Parameters wcstr 宽字符串的地址 mbstr 多字节字符串(ANSI)的地址 count 要转换的多字节的字符的个数 Example /* MBSTOWCS.CPP illustrates the behavior of the mbstowcs function */ #include <stdlib.h> #include <stdio.h> void main( void ) { int i; char *pmbnull = NULL; char *pmbhello = (char *)malloc( MB_CUR_MAX ); wchar_t *pwchello = L"Hi"; wchar_t *pwc = (wchar_t *)malloc( sizeof( wchar_t )); printf( "Convert to multibyte string:\n" ); i = wcstombs( pmbhello, pwchello, MB_CUR_MAX ); printf( "\tCharacters converted: %u\n", i ); printf( "\tHex value of first" ); printf( " multibyte character: %#.4x\n\n", pmbhello ); printf( "Convert back to wide-character string:\n" ); i = mbstowcs( pwc, pmbhello, MB_CUR_MAX ); printf( "\tCharacters converted: %u\n", i ); printf( "\tHex value of first" ); printf( " wide character: %#.4x\n\n", pwc ); delete[] pmbhello; delete[] pwc ; //该例子示例摘自msdn,我觉得这里有内存泄漏，所以我加入了 //最后两行，应为这里涉及到动态内存分配， //ms-help://MS.MSDNQTR.2003FEB.2052/wcecrt/htm/_wcecrt_mbstowcs.htm } Output Convert to multibyte string: Characters converted: 1 Hex value of first multibyte character: 0x0e1a Convert back to wide-character string:
